If pkgsrc is out of sync, you may get some dependency that is required
like foo>=0.20 but then if foo is old it could say building foo-0.19 and
then continue and fail later.
I think it should check if dependency is correct before starting to build.
Or maybe that can't be done easily because is done in a sub-process that
doesn't have this knowledge?
